To estimate \( 21,521 \div 52 \), we can round the numbers to make the division simpler.
1. Round \( 21,521 \) to \( 22,000 \) (since it's closer to \( 22,000 \) than \( 21,000 \)).
2. Round \( 52 \) to \( 50 \) (a simpler number to divide by).
Now we can perform the division:
\[
22,000 \div 50
\]
This can be simplified:
\[
22,000 \div 50 = 22,000 \div 5 \div 10 = 4,400 \div 10 = 4,400
\]
So, the estimated result of \( 21,521 \div 52 \) is approximately **400**.
